Harford health officer: Should I resign for giving mask medical advice to marching band?

Last week a local politician asked me to resign as health officer because I had given my best advice on how to protect a school marching band during a 4th of July parade. Horns and woodwinds expel aerosols much farther than breathing and speaking, so even an outdoor performance with an infected musician could spread COVID-19 to other players and to the crowd.
